Deep Sea Food Web
21
In every ecosystem there is a food web that keeps the number of each organism stable. If in the deep sea ecosystem, a primary producer, such as the diatom, went out, there would be a large disruption in the food web. First, primary consumers like shrimp and copecods will start to decrease in number. This means that the secondary consumers (lantern fish and ocean sunfish) will have less food to eat, resulting in a decrease in their numbers. This continues up the food chain until it reaches the top predators.

Sun's Energy
Phytoplankton is the base of the marine food web. They are the primary producers in their environment which means they are able to use light energy to convert carbohydrates through photosynthesis. During photosynthesis, phytoplankton uses carbon dioxide, sunlight, and water to produce glucose and oxygen.
